The second stage will be the "Shake Down" phase, this will be a sort of wargames period. The Open Payment Alliance will pre-load the network with up to 1000 bitcoins, all of which will be constantly traversing the network. The bitcoins on the network will all be real and they will be involved in binding transactions that will be occurring during this phase. The purpose is to try and break (or break into) the system. Anything you can come up with in terms of an attack will be fair game on the network during this time. Our goal during this time is to learn how well the network and our reference stack can withstand sustained assaults, attacks and threats. All the money you can capture during this phase will belong to you, no questions asked. Our most significant goal is to learn how to analyze and defend against the attacks, so while we would appreciate any information you can provide, it's not strictly necessary. This period is expected to last 1 to 2 months and during this time there will be a public scoreboard on the OPA website where you can see who got away with what and how they did it, (in as much as we are able to determine these facts).
So, when will the "Shake Down"-phase commence? I got
/r/netsec all worked up about it, I sure hope it will become reality.
